It is configured. The facility number data 33 is a value unique to each route.

Now, the node end will be described with reference to FIG. For a preset highway or toll road, the whole country is divided into meshes as shown in FIG. 3 (a).

Then, as shown in a partially enlarged view of the area AR of FIG. 3B, a mesh (for example, indicated by a symbol MS).
The intersection of the boundary line of No. 1 and the expressway or toll road is set as a node end (indicated by symbols NT _{10 to} NT ₁₆ ). In this case, the size of the mesh is, for example, 1 km square.

Between the node ends (NT ₁₂ -NT ₁₃ ), the road shape between the node ends is approximated by a plurality of straight lines.
As shown in FIG. 3C, nodes (N _{10 to} N ₁₃ ) indicating one end of each straight line are assigned.

Next, with reference to FIGS. 4 to 6, facility search data used in the highway mode will be described.
The facility search data 35 roughly corresponds to the route number data 32 of the highway information data 30 as shown in FIG. 4, and is composed of index data 36 representing each storage address of facility data 38 described later and index data 36. And a facility data group 37 including a plurality of facility data 38 to be searched.

Prior to the description of the facility data group 37, an example of a high speed facility will be described with reference to FIG. As an expressway facility on the α expressway, an A interchange (IC), which is the starting point of the α expressway, and a B service area (SA) existing in the downward direction from the A interchange,
Further, there is a C junction (JCT) existing in the downward direction and branching to the β motorway.

The distances between the high-speed facilities when going in the down direction are as shown below. A interchange-B service area: a ₁ B service area-C junction: b ₁ Also, the distance between each high-speed facility when going in the up direction,

Installation facility of the facility (gas station, restaurant,
It is provided with installation facility data 46 representing a souvenir shop and position data (specifically, latitude data and longitude data of the B service area) 47 representing the location of the facility.

Next, the operation will be described with reference to FIGS. 7 to 14. In the following description, the transition from the normal map mode to the highway mode will be described as being performed by the user's manual setting.

First, various variables are initialized (step S
1). Next, a high speed exit search is performed (step S2). The high-speed exit search is a search for which exit is the display target so that the user can distinguishably display the exit from the highway to the general road.

More specifically, when the high speed exit search is performed, it is determined whether or not the route is set in advance. When the route is not set by this, the processing is performed assuming that the high speed exit has not been set, that is, the exit has not been determined yet at the present moment.

When the route has already been set, the latitude data and the longitude data of the interchange set as the exit are acquired. Then, the process proceeds to the main process routine (see FIG. 8) (step S3).

In the main processing routine, the background is drawn on the CRT (step S21), and the key guide 50 is drawn as shown in FIG. 12 (step S22). Here, the key guide 50 is a message area for command input drawn in the shape of a key switch on the CRT.

Next, the system controller 5 causes the CD-R
The highway information data 30 is acquired from the CD-ROM (DK) via the OM drive 12 (step S2).
3). The system controller 5 determines based on the acquired highway information data 30 whether or not a high-speed facility ahead of the traveling direction is detected (step S24).

In the determination of step S24, when a high-speed facility is detected ahead of the traveling direction, the facility data group 37
Is determined whether it is necessary to load (step S
25).

If it is not necessary to load the facility data group 37 in the determination of step S25, the process proceeds to step S27. If it is necessary to load the facility data group 37 in the determination in step S25, the facility data group 37 is loaded (step S26).

Here, loading of the facility data group 37 will be described with reference to FIG. Index data 36 of the facility search data 35 based on the route number data of the highway information data 30 obtained in step S23
And the corresponding facility data group 37 is referenced.

Next, among the plurality of facility data 38 constituting the facility data group 37 referred to, facilities corresponding to all the facilities located in front of the current position of the vehicle in the traveling direction and reaching the end point of the route. All the numbers of the data 38 and the unique number of the facility are obtained.

More specifically, as shown in FIG. 13, when there are 50 facilities with specific numbers = 1 to 50 on a certain route, the facilities ahead of the vehicle position P in the traveling direction (specific number = 20 to ... 50) The number of facilities = 31 and the unique number = 20 to 50 are calculated.

In this case, the unique numbers of the facilities ahead in the traveling direction are continuous, but when some facilities are present only on the route opposite to the traveling direction, the unique numbers are not necessarily continuous. Not necessarily. Continuing,
It is determined whether it is necessary to initialize the cursor position (step S27).

If it is not necessary to initialize the cursor position in the determination in step S27, the process proceeds to step S29. In the determination of step S27,
When it is necessary to initialize the cursor position, redisplay is performed based on the stored cursor position.

Here, the initialization of the cursor position will be described in detail. For example, in the case shown in FIG. 12, in the facility name display, due to the restriction of the display area of the CRT screen,
The number of facilities that can be displayed at one time is four.

Therefore, the reference initialization position of the cursor position is
The closest facility in front of the traveling direction, that is, in the case of FIG. 13, the facility with the facility unique number 20 is set as the reference initialization position.

More specifically, in FIG. 12, the closest facility in front of the traveling direction is displayed as the Kohoku parking area. Also, if you enter a different route from the middle, or if you pass the facility corresponding to the cursor position in the previous initialization and the closest facility ahead in the traveling direction is changed, etc. The cursor position is initialized.

However, even if the facility corresponding to the cursor position has been passed in the previous initialization and the closest facility ahead in the traveling direction has been changed, a key check process described later (step S12). In, when the cursor position is changed by the up and down keys that move the cursor position up and down on the screen, if it is on the same line and the facility corresponding to the cursor position of the change destination has not yet passed, No initialization is done.

Subsequently, the facility data 38 is referenced (step S29), and the distance to the facility (total distance) is calculated (step S30). Here, the calculation of the total distance will be described with reference to FIG.

First, the closest node N ₁ ahead of the current position P of the own vehicle in the traveling direction is determined, and the position coordinate data (latitude data and longitude data) of the node N ₁ is obtained. Then, based on the current position coordinate data (latitude data and longitude data) which is the position coordinate data of the current position P, the distance L ₁
To calculate.

Similarly, the distances L _{2 to} L ₄ are calculated based on the position coordinates of the node N ₁ , the node N ₂ and the node N ₃ . Subsequently, the distance L ₅ is obtained by referring to the distance data 31 of the highway information data 30 corresponding to the node end NT.

Based on the calculated distances L _{1 to} L ₄ and the obtained distance L ₅ , the total distance is calculated by the following equation. Total distance = L ₁ + L ₂ + L ₃ + L ₄ + L ₅ Next, the route name drawing area 51 (see FIG. 1) at the top of the screen of the CRT.
The route name is drawn in (see 2) (step S31).

Then, a plurality of facility names corresponding to the current cursor position are drawn in the facility name drawing area 52 (see FIG. 12) (step S32).
